We typically use a simple RAID 1 configuration with 2 hard driives, and a System/Data partition, with the obvious goal of being able to continue operating if one drive fails. Our latest system shows two RAID Arrays: Partition 1 (System) was created (Array 00), and then the RAID configured, and then Partition 2 (Data/Shares) was created and this became Array 1. Disk Management shows a Disk 0 (500GB) and a Disk 1 (1.5TB), so Windows Server thinks that the partitioned drive is actually two separate disks. If this is a good way to configure the system I'd like to know; remember our only goal is to have redundancy in the event of a single hard drive failure. If not I'd like to know about it before it goes into production. Thx in advance!
You shure, that are two arrays created, not two LUNs? Just enter into Intel RAID utility at boot (CTrl+I usually) and check, how much arrays present there. If one RAID1 array and two LUNs, its OK, if two arrays, that is possible a Matrix RAID configuration, where multiple arrays can be created on one disk set, although this should work too, i.e. if one drive dead, system still bootable.
According to the information provided, the RAID 1 configuration has been done properly and there is no reason to be concerned since you will have redundancy for both partitions in the event of a single hard drive failure. Basically, that is the way how Windows Disk mManagement sees the RAID 1.
